What can change a real London quote?

  • Property size and layout
  • Age and condition of existing wiring
  • Occupied versus empty property
  • Socket, lighting and circuit count
  • Standard or premium fittings
  • Access beneath floors and within walls
  • Making good, flooring and decoration

Local planning considerations

Dense access, parking, deliveries and contractor overheads can widen the spread between quotations, so use the figures as an early budget rather than a quote.

  • Allow separately for parking, loading, permits or restricted delivery windows where a property has difficult street access.
  • Flats and managed buildings can add landlord, freeholder or building-management requirements that are outside a basic works estimate.
  • Party-wall, structural and access costs should be checked independently on extensions, lofts and major internal alterations.

How the regional model works

The 1.28× factor places this planning estimate 28% above the national planning baseline. We keep that modelling assumption separate from the dated national benchmark so users can see exactly which part comes from an external source and which part is UK Home Costs modelling.
